Application filed April 16. 1913. Serial No. 761,464.

To all whom it may concern Be it known that I, DoNAmr Mummy, :1 subjectof the King of Great Britain, and residing at 3 Lombard court, in thecounty of London, England, have invented c/erta n new and usefulImprovements in Printers for Irinting-"lelegraph Systems, of which thefollowing is a specification, reference being had to the accompanyingdrawings, which form a part hereof.

This invention relates to improvements in printers of the typewriterclass, said improvements being primarily adapted and designed for use inprinters forming part of a printing telegraph system.

.The invention seeks to provide in such a printer mechanism which shallbe simple and rugged in structure and rapid and reliable in action forperforming the line feed operatiomthe carriage return operation and theoperation of feeding to the printer the I blanks which receive theprinted messages.

In the embodiment of the invention shown in the drawings, the Variousmechanisms of the invention are almost wholly mechanical, therebylargely avoiding the delicatencss of structure and operation' which ingeneral charm'tcrize electrical mechanisms heretolorc employed toaccomplish .the paper teed movements in electrically controlledprinters.

In the accompanying drawings forming part of this specification. and inwhich like reference numerals designate corresponding parts in theseveral figures, the invention is shown in its preferred form.

Figure 1 is a plan view showing the principal parts of the improvedprinter, the typewriter mechanism being removed. Fig. 2 is a rearelevation of the printer showing the platen of the typewriter in place.Fig. 3 is a sectional elevation on the line l-3 of Fig. 1 the partss25and 92 being added. Fig. 4 is a detail in plan view showing one of theselecting magnets and its comb.

Inthe operation of this linenfeed mechanism, when the pawl 72 is pulleddownward, it rocks into looking ongagement with wheel (55, the pawlcarrier (36 being, at the same time, rocked on spindle 64 against thepressure of its spring 70. A continued downward pull on the pawl rotatesthe wheel ()5 and with it the blank carrier until projection 67 strikesthe stop in 69, at which time the blank carrier will lave been carriedforward in its travel the distance from one line to the next. Jockey 75acts to' prevent the blank carrier from traveling too far when it isactuated by a suclden vigorous pull on the pawl and pawl carr'ier. Thisline feed mechanism may be actuated by any suitable devices. In the present instance, a cord and drum actuated by the pulley shaft 48 isemployed for this purpose. It is also preferred to employ the carriagereturn mechanism as the means for actuating the line feed mechanism. Accordingly, the same cord and drum, as shown in the drawings, foractuating the line feed mechanism is also employed for the carriagereturn operation. 9

Referring now to the carriage return mechanism. 78 is a drum looselymounted on pulley shaft 48 and to which is secured one end of the cord79 which passes over a stationary pulley 80, thence around a pulley 81mounted on the carriage 62 and to pawl 72 of the line feed mechanism towhich it is secured, see Figs. 9 and 7. The drum is arranged to becoupled and uncoupled with shaft 48 by means of a clutch having onemember 82 fixed to the drum T8 and the other member 83 fixed to shaft48. lVhen the coupling 82, 83 is closed, drum 78 winds up the cord,thereby actuating the line feed mechanism and also returning thecarriage and blank carrier to the position for begilc hing a new line.When the carriage reaches the end of this return mo ement or thereabout,a block 84 or the carriage comes in contact with a level 85 which isthereby moved to open the coupling and disconnect the drum from shaft48. This lever 85 is pivoted on the main frame and carries a pinprovided with a "friction roller 86 which works in a groove S7 in thedrum (see Figs. 2 and 3). The coupling 89, 83 is normally held open by adetent 88 and is provided with a spring which operates to close thecoupling when the detent is disengaged. This arrangen'wnt may hevariously em bodied. In the present instance, see Figs. 9 and 11, thedetent S8 is arranged [to on gage a lug S9 ci lam-.85 and hold thlrlever over against tho, retractile pull of ihc spring 90 secured at oneend to tie base and at its other end to the lever 85. Detent 88 is helddown byn spring 91 so that the detent may engage In; 89. Thus, whendclcnt (58 is lifted out of engagement with lug Rf. spring 90 shiftslever so that the latter. by means of its roller F45, moves the drum 7%and clutch member 812 along sha it 45* to close the coupling. When thecarriage on its return movement moves the lever 85 hacluvard and therebyopens the coupling, detent 88 engagcslup 89 to hold the lever over andthereby retain the clutch in open position.

The closing: of the clutch is under the control of the selectingdevices. -'\Vhen, therefore, the proper impulse or group of impulsesenergizes one or more ofthe selecting magnets, one of the crossbars 20moves iiiward to exercise this control. In the arrangement shown in thedrawings, the controlling device for the coupling 82, 8.; is in the formof a lever 92 pivoted at 93 on top of magnet 2, see. Figs. 3, 9 and ti.The forward end of this lever projects in close proximity to one of thecrossbar-s 20 and the rear end projects beneath the free end of detcnt88, the forward end of the lever being tilted up and normally held inthis position by a spring 94. The -ft)l'\\'tlltl end of lever 92 isprovided with a sliding extension 95. It is secured to the lever 92 bymeans of pins 96 and 97 which pass through slots J8 and 90 in theextension, thereby permitting the extension to have longitudinalmovement on the lever. The oXtOllSlul] )5 is' held forward by a spring:100. one end of which is secured to a pin on the lever and the other endof which is secured to a pin on the extension. The forward end of theextension is pro vided with a pin 101. When the proper crossbar movesinward. it [mshcs the eX-. tension 95 backward into the path of thestriker bar 21) with the pin it)! back of the striker bar. When, now.the striker bar de- .*:cends it engages (Ktension )5 in advance of pinlOl. tilting the bar downward and thereby lifting dclcnt 88 fromengagement with in; 99. During this downward movement of the striker barpin it)! keeps extension 05 from sliding forward out of engagement withthe striker bar. The clutch on the. coupling: 82, SI thereupon closes inresponse to the action of sprh e; no which shifts lever 85. When thestriker bar moves to its upper position lever 92 returns to its initialpositionv with its extension 05 thrust forward to its initial position.'Detent 8.8 is thus released from lever 92, so that it is ready again toengage lug 8!) when Tenor-85 is moved back to open coupling 8'2, 83 uponthe return of the earring; i

determined position and always terminates ,lts travel in-this same islocked between latch 123 and stud 122 and the blank feed clutchmechanism is in the locked position of rest. A complete rotatlon of gear119 will, therefore, feed up a .fresh blank so that the beginning of theblank is at the printing point for a ncw message. When the last linefeed move ment of the blank carrier has been made in .the writing of agiven message and the car- Mi riage has been returned to startingposition for the beginning of a new line on a fresh blank, stud 130 ongear 129 may occupy any one of vztrious angular positions, dependent uon the length of the message just comp eted. Consequently, when theblank feed mechanism operates to feed in new blanks stud 122 may travelthrough various distances before it engages stud 130, such distancesvarying in accordance with the angular position of stud 130. The blankfeed travel ofthe blank carrier may be varied to suit the length ofmessage blanks employed by changing the ratio of gears 129 and 127. Butthe blank carrier will be always brought back to the same startingposition pre'ueten mined by the stopping position or limit of It will beclear, therefore, that the driving element is arran ed to actuallypropel the blank carrier through variable distances to the end of'theblank carriers travel at which time a. new blank will have been fed tobring the beginning of the blank to the printing point.

Latch 123 acts to lock stud 130 against stud 122 so that gear 119 andthe blank carrier move together and stop simultaneously. If stud 130 isahead of stud 122 when gear 119 begins to turn, then when latch 123meets stud 130 the latch slides back to permit stud 122 to engage stud130 whereupon the latch Springs outward'to lock stud 130 in place. Atthe end of the blank feed move ment the transverse letter feed movementof the carriage carries stud 130 laterally from the stud 122 and latch123 on gear 119, which is ready to repeat its operation at the end ofthe next carriage return movement.

In'th'e present embodiment of the invention the blank feed mechanism iscontrolled by the selecting devices, see Figs. 14, 17 and 18. For thispurpose trip 1141 fixed on a rock shaft 133, a lever 13 1 being securedat one end to this shaft and at its other end to an arm 135 having ahook 136 at its upper end designed to be engaged by a pin 137 on lever34. Arm 135 is normally held forward so that its hook is out of the pathof in 137, when lever 34 is workin. g the striker bar in the printingoperation, y a spring 138 and is pushed back to bring the hook into thepath of the pin by a spring retracted rod. 139 whose forward end extendsinu position to be acted upon b one of the cross bars 20 when selected)y the combs 17. When arm 135, which controls the coupling 108, 109, hasbeen pushed back, as described, it is retained in its set. position,until engaged by pin137 by a notched lever 140, which is pressed upwardby a spring 142'to engage with a pin 143 on arm 135. When lever 3 1rises and engages arm 135, rock shaft 133 is actuated to disengage trip1H. from coupling 108,100 and thereby set the blank feed mechanism inoperation. This movement of lever 3-1 carries pin 143 upward and out ofengagement with lcvcr 14-0. Before this movement has taken place thecrossbar and combs have been restored to normal position. When lever 34moves downward, by the quick action of spring 37 when released by com35, pin 137 recedes from hook 136 and spring 138 pulls arm 136 to itsforward position so as to be clear of pin 137 on the next upwardmovement of arm 34. Arm 135 is pulled down to its normal position andshaft 133 rocks trip 111 forward to engage pin 113 by the action of aspring 144 secured to a pin on shaft 133 and to a pin fixed on the mainframe. Thus, the parts are restored to normal position.
